Trader consensus on Polymarket clusters tightly around 16°C and 17°C at 28.5% implied probabilities each, driven by ensemble forecast models from ECMWF and GFS projecting Shanghai's March 25 high in the mid-teens amid a transitional spring pattern with southerly winds and partial cloud cover. Differentiating these close outcomes hinges on the precise timing and strength of a weak cold front nearing the Yangtze Delta—earlier passage favors 15°C (24% odds), while delayed advection of warmer moist air could nudge toward 17-18°C. Recent CMA updates confirm mild conditions without extremes, aligning with historical late-March averages of 14-15°C boosted by urban heat island effects and lingering El Niño influences; low odds for 20°C+ reflect negligible heat dome risk. Watch afternoon model refreshes for shifts.
